Courtreserve

First MCP server for CourtReserve — the racquet-sports club management platform that runs tennis, pickleball, padel, racquetball, squash, and badminton clubs. Talk to your club's members, reservations, events, and transactions from Claude, Cursor, or any MCP-compatible AI client.

What you can do with it

You:   "Find every active member at our downtown location whose membership
        expires this month and tell me which ones haven't booked a court
        in the last 30 days."
Claude: *calls list_memberships + list_reservations, joins the results, replies*

You:   "Register Sarah for the Tuesday evening pickleball clinic."
Claude: *calls register_for_event, confirms the result*

You:   "Cancel reservation 8888 and refund the booking fee."
Claude: *calls cancel_reservation + create_transaction (credit), reports back*

The MCP covers the same surface CourtReserve uses internally: members, memberships, families, court reservations, events (clinics, lessons, tournaments, round robins, open play), event registrations, transactions, courts, and locations.

Install

pip install -e .

For local development:

pip install -e ".[dev]"

Configure

CourtReserve's API uses HTTP Basic auth with two values issued from the club admin UI:

1. Log in to app.courtreserve.com as a club admin.
2. Go to Settings -> Additional Features -> Integrations -> API Access.
3. Click Create API Key. Enable the API access checkbox first if it's off.
4. Choose Full Access (read + write) or Restricted Access (pick specific roles).
5. Copy the Username (format: Org_<numeric>) and Password (long opaque string).

export COURTRESERVE_USERNAME="Org_12345"
export COURTRESERVE_PASSWORD="98765_550e8400-e29b-41d4-a716-446655440000"

The API key must be enabled on an Advance / Momentum / Enterprise plan (per CourtReserve's docs, the API add-on is paid). The key's role-based permissions control which endpoints the MCP can call.

Claude Desktop / Cursor

Add to your claude_desktop_config.json (or ~/.cursor/mcp.json):

{
  "mcpServers": {
    "courtreserve": {
      "command": "courtreserve-mcp",
      "env": {
        "COURTRESERVE_USERNAME": "Org_12345",
        "COURTRESERVE_PASSWORD": "your-password"
      }
    }
  }
}

Engineering standards

This MCP inherits the engineering playbook applied across the sanjibani MCP portfolio:

• Shared httpx.AsyncClient with connection pooling + transport-level retries.
• Typed exception hierarchy (CourtReserveAuthError, NotFoundError, RateLimitError, APIError, ConnectionError) with structured fields (http_status, request_id, retry_after).
• Application-level retry with exponential backoff + full jitter on 429/5xx, honoring Retry-After.
• isError-compliance (per the Blackwell Systems MCP security audit): tools raise exceptions, FastMCP wraps them with isError=true on the wire. AI agents can distinguish failures from successful responses returning error-shaped strings.
• JSONL audit logging via src/courtreserve_mcp/audit.py — one record per tool call to stderr (or <PKG>_AUDIT_LOG file). Fail-open: sink failure never breaks the tool. Secret redaction on password/api_key/token/etc.
• respx for httpx mocking + hypothesis property tests + pytest-asyncio.
• mypy --strict clean, ruff full rule set clean, py.typed marker (PEP 561).
• src/ layout, dynamic version from __init__.py, hatchling backend.
